ABSTRACT

SUMMARY:

The career of a sprinter is analyzed with U. Bolt achievements as an example. The effects of the increase of body mass and ageing are discussed within the framework of the polynomial models for the velocity, muscular isometric force and age. The analysis presented demonstrates the influence of the BM factor in analyzed racing. The nonlinear increase of the BM for 9 kg in the period 2009 - 2017 in was one of the reasons of Bolt's unsuccessful attempt to repeat or confirm the time 9.58 s. Another limiting factor was the fact that due to the age, Bolt was not able to increase isometric muscular force which, after the year of maximal efficiency (2009) decreased.
RESUMEN
RESUMEN La carrera de un velocista se analiza con los logros de U. Bolt como ejemplo. Los efectos del aumento de la masa corporal y el envejecimiento se discuten en el marco de los modelos polinomiales de velocidad, fuerza isométrica muscular y edad. El análisis presentado demuestra la influencia del factor MC en el análisis en las carreras. El aumento no lineal de la MC para 9 kg en el período 2009 - 2017 fue una de las razones del intento fallido de Bolt de repetir o confirmar el tiempo 9,58 s. Otro factor limitante fue el hecho de que debido a la edad, Bolt no fue capaz de aumentar la fuerza muscular isométrica que disminuyó luego del año de máxima eficiencia (2009).
